O. TORlGlANl TIME CONTROLLED SWITCH Filed Feb. 14, 1934 2 Sheets-Sheet 2 Patented Aug. 14, 1934 NETE@ STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in switches of the time controlled type, and more particularly to a switch especially adapted for use in controlling radios, lights, automatic stakers and the like.

The principal object or" the present invention is to provide a switch for opening and closing an electrical circuit automatically and in a positive and fool-proof manner.

Another important object of the invention is to provide a time controlled switch wherein the parts are capable of peing readily reached for the purpose of repair and replacement.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure i represents a rear elevational view of the clock, with a part of the back thereof broken away to disclose the switch means.

Figure 2 represents a top plan view of the clock, with a part of its top broken away to disclose the switch mechanism and its association with the clock mechanism.

Figure 3 represents a fragmentary vertical sectional view 'through the set starting dial shaft, showing the trip means.

Figure i Arepresents a fragmentary top plan View showing the elements disclosed in Figure 3.

Figure 5 represents a fragmentary horizontal sectional View through the gear and release means shown in Figure 3.

Figure 6 represents a perspective View of the stationary panel and contact carrier.

Figure 7 represents a perspective View of one of the contactors, associated with the starting switch.

Figure 3 represents a perspective View of the contacter employed with the stopping switch.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the numeral generally refers to a clock having the conventional clock mechanism. Numeral 6 lrepresents the usual alarm setting shaft equipped with the gear 7 which meshes with the clock mechanism gear train. At the forward end of -the shaft 6 is the pointer 8 cooperating with the usual dial on the face of the clock (not shown) while the rear end of this shaft is equipped with the operating knob 10.

The gear 11 is splined to the shaft 6 and a spring l2 serves to normally urge the hub 13 of this gear against the lug 14 carried by the shaft 6. The hub 13, as shown in Figures 3, 4 'and 5, is provided with a cut-away portion 15 and when the lug le falls into this cut-away portion 15, it releases the spring 12 which carries the di-electric block 16 at its free end. The spring 12 has lugs 17 which engage around the edge portion of this block 16 to retain the same,

while a contact 18, provided with lug members 19, is secured to this block 16 by engaging the lugs 19 around the edge portion of the plate 16.

This contact 18 operates in the path of the stationary spring contact 20 carried by the stationary panel 21 of insulation supported by the front frame plate 22 of the clock mechanism.

lA bracket 23 connects the plate 21 to the frame plate 22.

The stopping switch mechanism consists of a stem 25 having a pointer 26 at its forward end for operating with the usual dial on the face of the clock (not shown). This stem 25 carries a lug 25a for operating with the cut-away hub 27a of the gear 23 on the stem 25 which is splined to the shaft 25, as is the gear 1l to the shaft 6. A spring arm 29 having one end secured to the frame of the clock mechanism serves to normally urge the gear 23 against the lug 25a and when the gear 28 rotates to a predetermined position, the lug 25a will register with the out-away portion of the hub 27a, so that the gear will shift forwardly and release the spring 29, which spring carries the dielectric block 30, while the block in turn carries the contact band 31. This contact element 31 is in the path of the depending spring contact 32 on the panel 21. It will be observed that both the springs 12 and 29 are notched at their intermediate portions, as at 33, to receive the corresponding shafts 6 and 25.

A push-pull switch 34 is employed and suitably secured to the side of the clock whereby the clock mechanism can he entirely cut out of the radio circuit so that the switch of the radio (not shown) can be used alone to control the radio.

Figure 2 discloses the relationship of the switches, the starting switch being employed to close the radio circuit, while the stopping switch is employed to open the circuit at some predetermined future time.

While the foregoing specification sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:-

A time controlled switch comprising a clock mechanism, a pair of shafts geared to the'clock mechanism at the same geared speed, a switch controlled by one of the shafts for closing a circuit at a predetermined time, a switch associated with the other shaft for opening a circuit, at a `predetermined time, each of the said switches including a contaotor, and a panel of insulation common to both of the said contactors provided with a pair of contact members thereon in the path of corresponding contactors.
